T 0 cZZ whom, it may concern: Be it known that 1, ROBERT H. BEAU- MONT, a citizen of the United States, residing in Radnor, Delaware County, Pennsyl- Vania, have invented certain Improvements in Skip-Hoist Buckets, ofwhich the following is a specification.

The object of my invention is to improve the construction of a skip hoist bucket so in as to allow the front wheels when -they strike the platform or other stop to yield to a certain extent when discharging a load so that the blow will be cushioned and thus prevent the rapid destruction of the bucket and the parts connected therewith.

In the accompanying drawings:

Fig. 1 is an enlarged side view of a skip hoist bucket embodying the features of my invention; f

Fig. 2 is a View looking in the direction of the arrow in Fig. l, and I Fig. 3 is a detail perspective view of one of the forward axle mountings of the skip hoist bucket.' i

Referring to the drawings it-will be seen that the present invention embodies a bucket 8 especially adapted for use with a well known and widely used type of skip hoist (not shown). The bucket 8 is open at the top to receive material from a car, scoop or other feeding or supply mechanism. Secured at or near the rear end of the bucket is an axle 12 rectangular in cross section and mounted on the reduced ends of the axles are. wheels 13. At the oppositeor forward end of the bucket is a rectangular axle 16 which is mounted in a guide frame 18 secured to the bucket, and on the reduced ends 14 of the axle are wheels 15.

Abolt 17 extends through each guide frame and through the axle as shown and a spring 19 is mounted on each bolt between the rear end of the frame 18 and the axle iso that the axle will normally rest againstthe opposite or forward end of each frame as shown in Figs. 1 and 3. 21 is a bail, in the present instance, connected to a link 22, pivoted to the axle 12, although an ordinary connection may be used without departing from the essential features of the invention. A suitable hoisting rope .or cable bucket construction from a conventional skip hoist or similar apparatus is attached to the bail 2].. The guide frames 18 and bolts 17 afford a rigid and positive support for the front axle 16 and confine and guide the axle against movement in all directions except in a direction parallel to the bolt 17 on which the axle is slidably mounted.

In; the operation of the device, the rope or cable of the conventional skip hoist or other similar apparatus is attached to the bail 21, which operates to move the bucket 8 along suitable tracks until the front wheels 15 or axle 16' contact with a platform or positive stop mechanism on the skip hoist or similar apparatus, when the bucket is brought to a sudden and abrupt stop. Were it not for the provision of the improved cushioning means above described, such impact would tend to loosen or'wea-ken the parts of the bucket and also'parts of the skip hoist or the like structure. In the mounted the front axle in the guide frames and have provided spring means which yield when the wheels or axle contact with the positive stop, thus materially cushioning the ,blow and preventing breakage or damage of the bucket or hoist parts or sudden jarring of such mechanisms.

While I have shown a particular arrangement or means for checking the shock when the front wheels or axle strike the stop, other means will readily suggest themselves without departing from the essential features of the invention.

I claim:

1. A skip hoist bucket comprising a body, an axle, means for securing the axle to the body against movement in all directions except one and yieldable means for resisting the movement of the axle in the direction in which it is free to move.

2; A skip hoist bucket comprisinga body,

guide frames secured to the body, an axle siidably fitted in the guide frames and normally engaging the forward ends thereof, spring means for resisting rearward sliding movement of the axle and positive means for constraining the axle to rearward sliding movement.

3. A skip hoist bucket comprising a body above described, I have portion, guide frames secured at each side of the body portlon, a rectangular axle arranged to slide in the guide frames and huvlng openings extending through "the 5 same near the ends thereof, Wheels carried by the axle, e longitudinal bolt extending through each gulde frame and through the emme openings in the said mile, and a spring surrounding each longitudinal bolt and inter posed between the axle and each of the guide frames so as to press the axle forward and to allow the same to yield when the wheels strike a stop.

ROBERT H. BEAUMONT.
